To all whom it ma z'co ncem: Be it knownt at I, JOHN A. SECOR, a

citizen of the United States, residing at Laporte, in the county ofLaporte and State v of Indiana, have invented a certain new and usefulImprovement in Carbureters, of which the following is a specification.

My invention relates to improvements 1 n carbureters and is.illustrateddiagrammatically in one form in the accompanying drawing wherein isshown a transverse section through the device.

Like parts are indioated by like letters; I p v for the engine. Themixturejsg drawn from in the drawing.

The carbureting or vacuum chamber A has at one end the air mtake port Aand at the other endthe mixture discharge port A controlled respectivelyby the similar air intake and mixture discharge valves A A", adescription of one of which will sufiice for both.

The valve chamber B contains the cylindrical drum B opening at one sideinto the carbureting chamber and having perforate top and bottom walls BA valve stem B is slidably mounted in a sleeve B in the lower wall ofthe valve chamber and in a boss B in the upper wall thereof, and carries the two puppet valves B in opposition one to the upper and one tothe lower wall of the drum and concentric with the perforations in saidwalls and so arranged as to form balanced puppet valves.

A bracket C. slidably and adjustably mounted upon the wall ofthe'chamber A is held in position by the, cap screw C and supports thepivotally mounted block C slidably mounted upon the lever C andadjustably held in position therem by the set screw C. The counterbalanceC is slidably mounted upon the lever C on the side my drawing anoperative device, still many changes might be made both in size, shapeand arrangement of parts without departing materially from the spirit ofmy invention. Parts might be made or additional parts no added or someof the parts modified in position or shape without departing in any wayfrom thespirit of my invention. I wish,

in a sense diagrammatic. I

The use and operation offiny' ginvention are as follows: Water and fuelare supplied to the vacuum chamberthrough the" supply therefore, thatmy. rawing be regarded as nozzles, the opening of each of said nozzlesbeing adjusted in the usual manner by means of the needle valve tonrake'them responsive in their feed to that degree of vacuum in thecarbureting chamber which will furnish at all'times asuitable mixturethe carbureter into the engine ini 'the usual manner and needs no;further illustration. In order that thevacuum in the carbureting chambermay be controlled ,and adjusted responsive to the condition oftheengine, thereby giving a suitable .mixture for all power, speed andload, means must be employed for controlling simultaneously thoughdifierentially both vair intake and mixture discharge" ports. Thesemeans in my present invention take the form of balanced puppet valveswhich are given a differential movement by appropriately proportioningthe relative lengths of the lever arms controlling each of said valves.It will be observed that the bracket on the carbureter may be moved,thus varying the position of the fulcrum of the controlling lever, andthat when this is done some point will be reached at which any positionor valves are so positioned that they are what is known as balancedvalves and they operate therefore quite independent of and not aifectedby any change in the vacuum or pressure or any change in the velocity ofthe gases passing "by them. I have provided also a counterbalance weightwhich may be so adjusted in position as to counterbalance the weight ofthe connecting rod and the weight of the lever. The result, therefore,

is that I provide a completely balanced system in which the only loadcarried or moved by the overnor is the friction load, and in nvhich t egovernor may be made peculiarly sensitive in view of the fact that thereis practically 'no resistance to or drag upon its operation, due eitherto any variations in the velocity or absolute pressure of the gas or tothe force of gravity acting upon the moving parts. Of course, otherdevices of valves and other balancing systems,might beused wherein thesystem would still be balanced in every respect and wherein thevariation in the operation of the carbureter or the engine would in nowise vary the load on the governor. Atthe same time, however, I havedeemed it expedient for the purpose of this invention to illustrate itas applied to puppet valves connected by an adjust-able controllinglever.

I claim:

1. A carbureter having a fuel inlet and.

ment of the valve, and-means for operating said valves simultaneouslybut unequally and a balancing device associated with said valveoperating means, whereby the two sides of such movable valve system areat all times in mechanical balance.

3. A carbureter, having a vacuum chamber having fuel and Water inletseach having a nozzle opening into the carbureter chamber separate anddistinct one from the other and adapted to vary but unequally theirfeeds responsive to variations in the vacuum in the carbureter chamber,air intake and mixture discharge ports and balanced piston valvescontrolling said orts,

and means for operating said valves simul-- taneously but unequally.

4:. A carbureter, having a vacuum chamber having fuel and'water inletseach having a nozzle opening into the carbureter chamber separate anddistinct one from the other and adapted gi/vary but unequally theirfeeds responsive to variations in the vacuum in the-carbureter chamber,air intake and mixture discharge ports and balanced piston valvescontrolling said ports, and means for operating saidvalvessimultaneously but unequally, and adjustable connections between the twovalves whereby their relation can be varied at will.
